Installation function
An air/water-heat pump installation exploits outdoor air to heat up accommodation. The conversion of the outdoor air's energy to accommodation
heating occurs in three different circuits. *From the outdoor air, (1) , free
heat energy is retrieved and transported to the heat pump. In the refrigerant circuit, (2) the heat pump increases the retrieved heat's low temperature to a high temperature. In the heating medium circuit, (3) the heat
is distributed around the house.
A
B
C
D
E
F
G
H
Outdoor air
The outdoor air is sucked into the heat pump.
The fan then routes the air to the heat pump’s evaporator. Here, the air
releases the heating energy to the refrigerant and the air's temperature
drops. The cold air is then blown out of the heat pump.
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a refrigerant, which
also passes the evaporator. The refrigerant has a very low boiling point.
In the evaporator the refrigerant receives the heat energy from the outdoor
air and starts to boil.
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas's temperature increases considerably, from 0 °C to approx 80
°C.
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the indoor module, whereupon the gas
is cooled and condenses to a liquid form again.
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is retrieved
by the indoor module's water, the heating medium, which is heated to 55
°C (supply temperature).
The heating medium circulates in a closed system and transports the heated
water's heat energy to the house radiators/heating coils.
The temperatures are only examples and may vary between different installations and
time of year.

Maintenance of VVM 320
Regular checks
Your indoor module is, in principle, maintenance free and therefore requires minimal care after commissioning. On the other hand, it is recommended that you check your installation regularly.
All servicing must be carried out by a person competent for the job.
If something unusual occurs, messages about the malfunction appear in
the display in the form of different alarm texts. See alarm management
on page 69.
Safety valve
The water heater's safety valve sometimes releases a little water after hot
water usage. This is because the cold water, which enters the hot water
coil, expands when heated causing the pressure to rise and the safety valve
to open.
1. Open the valve.
2. Check that water flows through the valve.
3. Close the valve.
NOTE
Do not remove or adjust any components that are part of this pressurised
water heater. Contact your installer!
NOTE
If this pressurised water heater develops a fault, e.g. a flow of hot water
from the overflow pipe, turn the heat pump off and contact your installer.

Saving tips
Your installation produces heat and hot water. This occurs via the control
settings you made.
Factors that affect the energy consumption are, for example, indoor temperature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
႑ Open the thermostat valves completely (except in the rooms that are to
be kept cooler for various reasons, e.g. bedrooms). The thermostats slow
the flow in the heating system, which the indoor module wants to
compensate with increased temperatures. It then works harder and
consumes more electrical energy.
႑ You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See page 61 for instructions.
႑ If you activate "Hot water Economy", less energy is used.
႑ You can influence the energy consumption by connecting the indoor
module to different supplements such as solar, gas or oil.

Increasing the indoor temperature one degree increases the energy consumption by approx. 5%.
Domestic electricity
In the past it has been calculated that an average Swedish household has
an approximate annual consumption of 5000 kWh domestic electricity/year. In today's society it is usually between 6000-12.000 kWh/year.

Energy meter
Check the accommodation's energy meter regularly, preferably once a
month. This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
heating curve offset and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

The slopes of the heating /cooling
curves indicate how many degrees
the supply temperature is to be increased/reduced when the outdoor
temperature drops/increases. A
steeper slope means a higher supply
temperature for heating or a lower
supply temperature for cooling at
a certain outdoor temperature.
The optimum slope depends on the climate conditions in your location, if
the house has radiators or under floor heating and how well insulated the
house is.
The curve is set when the heating installation is installed, but may need
adjusting later. Normally, the curve will not need further adjustment.

In the event of making fine adjustments of the indoor temperature, the
curve must be offset up or down instead, this is done in menu 1.1

4 Disturbances in comfort
In most cases, the indoor module notes operational interference (operational interference can lead to disturbance in comfort) and indicates this
with alarms and shows action instructions in the display.
Info-menu
All the indoor module measurement values are gathered under menu 3.1
in the indoor module menu system. Looking through the values in this
menu can often simplify finding the fault source.
Manage alarm
In the event of an alarm, some kind of
malfunction has occurred, which is
indicated by the status lamp changing
from green continuously to red continuously. In addition, an alarm bell
appears in the information window.
/RZ SUHVVXUH DODUP

Alarm
UHVHW DODUP
DLG PRGH
In the event of an alarm with a red
status lamp a malfunction has occurred that the indoor module cannot
remedy itself. In the display, by turning the control knob and pressing the OK button, you can see the type of
alarm it is and reset it. You can also choose to set the indoor module to
aid mode.
info / action Here you can read what the alarm means and receive tips
on what you can do to correct the problem that caused the alarm.
reset alarm In most cases it is enough to select "reset alarm" to correct
the problem that caused the alarm. If a green light illuminates after selecting "reset alarm" the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the problem that caused
the alarm remains. If the alarm disappears and then returns, contact your
installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
indoor module produces heat and/or hot water despite there being some
kind of problem. This can mean that the indoor module's compressor is
not running. In this case the immersion heater produces heat and/or hot
water.
Chapter 4 | Disturbances in comfort
NIBE™ VVM 320
69
NOTE
To select aid mode an alarm action must be selected in menu 5.1.4.
Caution
Selecting "aid mode” is not the same as correcting the problem that
caused the alarm. The status lamp will therefore continue to be red.
If the alarm does not reset, contact your installer for suitable remedial action.
NOTE
Always communicate the product's serial number (14 digits) when reporting a fault.

႑ Too low hot water setting.
႑ Enter menu 2.2 and select a higher comfort mode.
Low room temperature
႑ Closed thermostats in several rooms.
႑ Indoor module in incorrect operating mode.
႑ Enter menu 4.2. If mode "auto" is selected, select a higher value on
"stop heating“ in menu 4.9.2.
႑ If mode "manual" is selected, select "heating". If this is not enough,
select "addition".
႑ Too low set value on the automatic heating control.
႑ Enter menu 1.1 "temperature" and adjust the offset of the heating
curve. If the room temperature is only low in cold weather the curve
slope in menu 1.9.1 "heating curve" needs adjusting up.
႑ "Holiday mode" activated in menu 4.7.
႑ Enter menu 4.7 and select “Off”.
႑ External switch for changing the room heating activated.
႑ Check any external switches.
႑ Air in the climate system.
႑ Vent the climate system

႑ Enter menu 1.1 (temperature) and adjust the heat curve offset
downwards. If the room temperature is only high in cold weather the
curve slope in menu 1.9.1 (heating curve) needs to be adjusted down.
႑ External switch for changing the room heating activated.
႑ Check any external switches.
Low system pressure
႑ Not enough water in the climate system.
႑ Top up the water in the climate system.
The compressor does not start
႑ There is no heating requirement.
႑ The indoor module does not call on heating nor hot water.
႑ Temperature conditions tripped.
႑ Wait until the temperature condition has been reset.

Additional heat:
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for example, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
Buffer vessel
A buffer vessel increases the system volume and removes the unwanted
temperature variations that can otherwise be sent out on the climate system. This ensure the running of the heat pump and reduces the heat spikes
that could otherwise be heard from the climate system.
Calculated flow line temperature
The temperature that the indoor module calculates that the heating system
requires for an optimum accommodation temperature. The colder the
outdoor temperature, the higher the calculated supply temperature.
Charge pump
See "Circulation pump".
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
Climate systems can also be called heating systems. The building is heated
using radiators, under floor coils or convector fans.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
Convector
Works in the same way as a radiator, but with the difference that the air
is blown out.

Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
An operational interruption in the indoor module can sometimes be noticed as disturbances in comfort.
In most cases, the indoor module notes operational interference and indicates this with alarms and shows instructions on how to rectify it in the
display.
Domestic hot water
The water one showers in for example.
DUT, dimensioned outdoor temperature
The dimensioned outdoor temperature differs depending on where you
live. The lower the dimensioned outdoor temperature, the lower the value
should be selected on "selecting a heat curve".
Electrical addition
This is the electricity that, for example, an internal immersion heater uses
to cover the heating demand that the heat pump cannot manage.
Emergency mode
A mode that can be selected using the switch in the event of a fault, which
means that the indoor module stops. When the indoor module is in
emergency mode, the building and/or hot water is heated using an immersion heater.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Expansion vessel
Vessel with heating medium fluid with the task of equalising the pressure
in the heating medium system.
Flow pipe
The line in which the heated water is transported from the indoor module
out to the house's climate system (radiators/heating coils).

Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Heating curve
The heating curve determines which heat the indoor module is to produce
depending on the temperature outdoors. If a high value is selected, this
tells the indoor module that it must supply a lot of heat when it is cold
outdoors in order to achieve a warm indoor temperature.
Heating medium
Hot liquid, usually normal water, which is sent from the indoor module to
the house climate system and makes the accommodation warm. The
heating medium also heats the charge coil with the hot water.
Hot water heater
Container where domestic water is heated. Is located inside the heat pump,
but an extra hot water heater can be installed in the event of large hot
water requirements.
Container where domestic water is heated. Is located somewhere outside
the heat pump.
Outside sensor
A sensor that is located outdoors. This sensor tells the indoor module how
hot it is outdoors.
Radiator
Another word for heating element. They must be filled with water in order
to be used with VVM 320.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and during condensing,
gives off heating energy.
Return pipe
The line in which the water is transported back to the indoor module from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the indoor module after releasing the heat energy to the radiators/heating coils.

Room sensor
A sensor that is located indoors. This sensor tells the indoor module how
hot it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water side, when the heat pump
produces hot water.
Supply temperature
The temperature of the heated water that the indoor module sends out
to the heating system. The colder the outdoor temperature, the higher
the supply line temperature becomes.
